These are the first 4 upgrades you should make to your 2003-2007, 5.9L Cummins.

If you're just getting into the diesel game with a third-generation Cummins 5.9L you're on the right track. While people say the 12v motors are great for being able to handle lots of power and having lots of upgrades. The 24v is also a very solid choice for both of those same reasons. With more hp from stock than the 12v motors and some beefy internals, like forged rods that can handle over 800hp. There is lots of potential to be had. 

It's a great truck from the factory, but if you're anything like the rest of us you're not interested in keeping it stock. Especially with the number of bolt-on upgrades available for the 5.9L. Why not make a great truck even better? Today we will show you the first 4 mods you should do to your 5.9L Cummins turbo diesel. 

The newest turbo from Calibrated Power is definitely raising the bar for drop-in turbos.

When looking at replacing your stock turbo there's a lot to take into consideration; How you use your truck, your current needs, and the future goals for your Cummins.  With the success of the Stealth 64 for 5.9L Cummins, the team at Calibrated Power looked at how much more we can push the envelope. So, what can the 3rd Gen Stealth 67 get you?

03-05 Cummins Custom Tuning is Finally HERE!

For over a decade the diesel performance industry has been waiting for REAL custom tuning for their 2003 - 2005 Cummins.  These early common rail engines have dealt with box programmers and pressure boxes for long enough, finally there is a solution.

MM3 Tuning has been out for less than a year and has already made a big splash in the highly modified Cummins world.  With the capability to tune 1998.5 to 2017 Cummins this tuner has a wide range of support.  

However many different reasons there are for the success of this new Smarty based custom tuning platform I dont know, but the 3 reasons below are certainly the most common ones we here at Calibrated Power.

Smarty MM3 Tuning Update! 

We have been testing the new Smarty MM3 Tuning for the 1998.5 - 2016 Cummins. The software/hardware is the newest solution for custom tuning.  Until now, the  limited amount of accessible tables in the 1998.5-2002 tuning platforms made fine tuning challenging for highly modified Cummins trucks leaving them smokey, noisey,  and generally not as smooth as other similarly modified trucks tuned with more advanced software.  Now that we have access to said tables, we will be able to create clean, efficient power with these trucks.

One of the most exciting features to the new Smarty MM3 is Live Tuning.  The live tuning ability allows our tuners to make real-time changes to the calibration on the dyno or during a road test where in the past we had to wait 7-12 minutes to implement one change.  As you might imagine, live tuning will significantly shorten the developement cycle and allow us to quickly  fine-tune a wide variety of modifications on-site at CPS.   The second advantage to the live tuning software is the ability of the customer to change tunes (power levels etc.) on the fly on any of the supported platforms.  These power levels will be supplied along with the base tune to customer at the time of sale (idealy).  

Our discussion with the developers of this software/hardware package lead us to believe that improved scan tool functionality is next on the priority list.  We would expect to see a very high sample rate scan tool along with several dozen of the most important PIDs in the near future for beta testing.   This tool is critical to the development process.  Without a strong scan tool we cannot validate our work, the better the tool - the better the final product and the better we can help our customers troubleshoot accurately if they need to.
